The Havas Health agencies, now called Havas Health & You, had a rough first start to 2017, with Havas CFO François Laroze telling investors that the health agencies did not perform “very well” in the first half of the year.

Still, Laroze said he expects a rebound for the network’s health business in the second half of the year.

Havas in March announced that it had restructured Havas Health, which includes the H4B, Life, and Metro brands, and the Havas Creative Group’s global consumer health practices, creating a new entity known as Havas Health & You.

Donna Murphy, global CEO of Havas Health & You, said in an email that the health unit underperformed slightly for the first six months of 2017, “reflecting a timing issue.” She added that “we expect Havas Health & You to have a solid 2017.”

There may be a reason for her optimism. During the same second-quarter earnings call, held Friday, Havas CEO Yannick Bolloré said the health network won Bristol-Myers Squibb’s media business.

The new BMS business comes on the heels of another big U.S. win for Havas. Earlier this month Sanofi said it had named Havas Media as the U.S. media agency for its pharmaceutical business as well as its strategic planning partner for its consumer healthcare business.
